About this game
Math Craft turns mental arithmetic into a card-battling roguelite. Each turn deals number cards and operator cards; you assemble them into an equation, read its value live, and fire it at a monster. The elegant hook: hitting the enemy's remaining HP exactly lands a double crit - so every fight is a little arithmetic puzzle about landing on the perfect number. Overshoot carelessly and the overflow bruises you back. Operators divide only evenly, negatives are locked behind a relic, and a x² or ×3 card can appear to launch values into orbit. Between floors, three of twelve relics reshape the rules - true operator precedence, six-card hands, vampiric exact hits, soft overflow - while enemies scale across 24 floors and three elite bosses that only accept exact answers. Your best depth and lifetime equations persist, and the endless climb keeps a calculator in every pocket honest.
How to play
Tap a number, then an operator, then a number to build the equation, then press Strike. ÷ must divide evenly; the equation must start and end with numbers.
Tips & Tricks
- Build small first: a 12 that lands exact beats a 40 that overshoots
- Multiplication cards are gold - save them for the round the enemy sits on a multiple
- The precedence relic changes everything; relearn your instincts after picking it
- Skip a turn rather than feed the overflow bruise
Frequently asked questions
What counts as an exact hit?
When your equation's value equals the enemy's current HP, damage doubles - usually ending the fight on the spot.
Why did my division fail?
Division must be even: 8÷2 works, 7÷2 invalidates the whole equation. Check the live value strip before striking.
Does progress save?
Best floor and total equations persist; cards and relics reroll each run.
